Popularization of professional knowledge of disassembly and assembly methods for routine maintenance of imported bearings

The disassembly and assembly of imported bearings shall be carried out on time, and the disassembly and replacement of bearings shall be carried out. After disassembly, if it is used again, or the condition of the bearing must be checked, its disassembly and installation shall be the same as the time. Note that the bearing parts are not damaged, especially the actual operation difficulty coefficient of bearing assembly conversion.
It is also very important to make special tools for disassembly and assembly according to the requirements. During disassembly, according to the engineering drawings, scientifically study the disassembly mode and sequence, and investigate the mutual cooperation standards between the supports, so as to ensure that the disassembly work is safe.
On the outside of the transition fit for external installation and disassembly, several screws for external extrusion extruder screws are set on the circumference of the shell in advance, and the extruder screws are tightened evenly during installation and disassembly. The screw hole of extruder is usually covered by independent bearings such as plug and tapered roller bearing. When there are several openings in the shoulder, protective cushion blocks shall be used, which can be drilled or tapped. The disassembly and assembly of the inner hole can be pulled out with a punch, which is very simple. At this time, pay attention to make the borehole bear its tension.
Second, the drawing tools shown are also commonly used. No matter what kind of fixture, it must be stuck on the edge of the inner ring. Therefore, it is necessary to consider the specifications of the shaft support shoulder, or conduct scientific research when making and processing the groove on the shoulder, so as to facilitate the application of pulling fixture.
Steam pressure method is selected for inner hole disassembly of large and medium-sized bearings. According to the manifold steam pressure setting at the bearing inlet, it is easy to pull. The steam pressure method and pulling fixture are used to disassemble and assemble the full width bearing.
